新型声光控开关的研究与实验
首发时间:2008-12-02
摘要:公共场所照明用电的管理始终困扰着我们,普通开关控制不仅在黑暗中使用不便,而且由于没有及时关闭易造成浪费,尤其在教室等公共场所长明灯现象十分普遍,这造成了能源的极大浪费。本项目研究的是一种利用声,光双重控制且具有定时功能的无触点开关。开关控制电路有声控部分和光控部分组成,白天光控电路对外界光亮程度进行检测,输出与光亮程度相对应的电压信号,无论多大的声音干扰也不能开灯,从而实现白天灯泡不亮,晚上或遇到阴天,光敏电阻感受光强度并输出相对应的电压信号,遇到声响时,通过声控电路使灯泡自动点亮,并延时一段时间后熄灭,从而实现自动控制,而且对于声音感知的灵敏度和对光感知的灵敏度以及延时时间能够调节,也可以人为设定延时时间。它特别适用于住宅楼、办公楼楼道、走廊、仓库、地下室,厕所等公共场所的照明自动控制,是一种集声、光、延时、定时与一体的既节电又方便的自控开关。

The New Sound And Light Controlled Switch
Abstract:We always have a lot of troubles in the management of the lighting in public,the common switch is inconvenient in the dark,and it is easy to waste power because of not being shut down in time,especially the lamps that were kept alight exist widely in the classrooms and other public places,it costs lots of power unnecessarily.The project is about a kind of both sound and light controlled swich that has timing function,swich controlled circuit is consist of sound controlled part and light controlled part,the light controlled circuit detects the brightness outside in the day,and outputs the corresponding voltage signal,no matter how loud the sound is,the lamp can’t light up this moment,so lamp can’t light up in the day;at night or on a cloudy day, the photoresistance detects the light insensity and outputs the corresponding voltage signal, when sound appears, the sound controlled circuit lights the lamp,and it will go out in a period of time, so the lamp can be controlled automatically. The photosensitivity 、soundsensitivity and the delay time can be adjusted. And the delay time can also be setted by people. It applys to the autocontrol of the lighting in public places,such as residential building、corridor、storehouse 、basement 、toliet and so on, it is a kind of sound and light controlled and timing automatic switch which is convenient and saves the power.
